Sigma Software Group vs A-listware: overview
Sigma Software Group
Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.
A-listware
A-listware was founded in 2017 and is headquartered in London, UK, with an R&D center in Ukraine and a reported 51 to 200 employees. The company's core model centers on delivering remote engineering teams to clients, with embedded systems and IoT development, including firmware development, legacy system modernization, and hardware integration, named among its service lines. That staff-augmentation framing distinguishes it from project-based firmware consultancies: clients typically embed A-listware engineers into their own team and processes rather than handing off a defined firmware deliverable.
